The strength of coarse aggregate may be assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compression load. Aggregates possessing high resistance to crushing or low aggregate crushing value are preferred for use in high quality pavements.

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Hot Sale. MTM Grinding Mill. MB5X Grinding Mill.
BS 812 part 110 describes a method to determine the aggregate crushing value (ACV) which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load.The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve.
A082 Aggregate crushing value apparatus (ACV) ( Aggregates-Rocks ) Comparable to BS 812:110; Two models available: A082: Comprising 150 mm nominal diameter steel cylinder, plunger, base plate, tamping rod and measure 115 mm diameter x 180 mm deep. Used for aggregate passing 12.7 mm and retained by 9.52 mm sieve. Weight: 20 Kg approx. ...
Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. All parts directly coming in to contact with the specimen during the test are made of mild steel duly case hardened. Optional Accessories: The following accessories are not part of the standard ...
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred.
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value ...
The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
